SPECIFICATION forming part of Letters Patent No. 376,710, dated January17, I888.

. Application tiled September 26, 1887. Serial No. 250.606. (No model.)

To all whom it may concern.-

Be it known that I,WILLIAM H. H. DABNEY, a citizen of the United States,residing at Oakland, in the county of Pottawattamie and State of Iowa,have invented certain new and useful Improvements in Attachments forWindmill Pump-Rods; and I do declare the following.

to be a full, clear, and exact description of the following descriptionand claim when taken in connection with the annexed drawings, in whichaFigure 1 is aside view ofa portion of a windmill-rod, showing myimprovements applied. Fig. 2 is a view of another side of the same.

Figure 3 is a perspective View of one of the' springs removed from therod.

Referring by letter to the said drawings, A B indicate two sections,which in the present illustration I shall refer toas a windmill-rod].although it may be that of apump or the like. The rod, it will be seen,is made in two sections, so as to allow the same to give lengthwise, andthe ends are connected by a spring or yielding connection, as will bepresently explained. V

D indicates a spring, which may be formed of steel or other suitable"material. This spring has its body portion coiled, as shown at a, and

.the outer coil or whirl at each endis approximately straight, asindicated at b, being bent at right angles, so as to form short arms d,which are designed to be driven .into the sections of the rod. It shouldbe observed that these branches are secured to opposite sections of therod, so that a yielding connection is had.

By having one of the branches of the spring I to each section of the rodit will be seen that when thesaid sections have been separated theaction of the spring,which will exert great force to return the sectionsto meet again, Thus it will be seen that when any sudden jerk or unduemotion, which may result in strain to some parts of a mill, takes place,by the action of these spring-connections the rod will be al lowed toyield, and thereby ease its action and prevent damage to otherconnecting parts.

' the coils will be contracted, thereby increasing I In operation Iemploy two of these spring connections, such as shown in Fig. 3 of thedrawings, and I arrange them on opposite sides of the rod and securetheir'free ends into the sections of the said rod, so that when theparts are acted upon so that strain may occur the spring will becontracted a little, thereby exertinggreater force to return the partsof the rod as they increase the distanceof sepa ration. While I haveshown and described these springs as being made in two parts and." I

one placed-on each opposite sideof the meeting ends of the rod, yet itis obvious that two coils maybe formed from a single piece of material,'in'which case a straight transverse I porti'oh would be formed to passthrough or be secured to one section of the rod, Having described thisinvention, what I claim is;

The combination, with a windmill pumprod, of springs having coils, asdescribed, and having their opposite ends connected to the oppositesections of the rod, substantially as specified. 7 V

In testimony whereof I aflix my signature in presence of two witnesses.WILLIAM Hun. DABNEY. ,-Witnesses:
